The respected computer scientist Dahlia Malkhi criticized the upcoming Proof of Stake (PoS) system at Ethereum called Casper. She is enthusiastic about crypto currencies, but there is too little academic research on the security of protocols like Casper.

From Proof of Work to Proof of Bitcoin profit

The Proof of Work (PoW) system is effective when it comes to securing a Bitcoin profit network, but it requires a lot of power and thus pollutes the environment. Bitcoin profit mining will soon require as much electricity as Argentina, i.e. almost 140 terawatt hours or 0.6 percent of the world’s energy supply.

Proof of Stake is a solution to the energy problem. The PoS system secures the network by allowing participants to “stake” their coins. As soon as a user “sets” the digital currency, he has the opportunity to find the next block and receive a reward for doing so. The more digital coins you bet, the more likely you are to find the next block.

Proof of Stake – The vulnerabilities

The approach sounds tempting and easy to implement. In practice, however, there are several problems. The biggest problem is the “Nothing at Stake” problem. Suppose someone wants to attack the Bitcoin network. This person needs enough equipment to generate 51 percent of the future blocks. Nowadays this is more than unlikely. Miners also have to pay for their hardware, electricity and storage costs. This always gives them an incentive to mine the right blockchain and earn money.

The person is annoyed by Bitcoin and now chooses a PoS system. He first buys a large part of the coins and sets them to create fake new blocks. Other, honest Staker would lose nothing now, if they would create the right and wrong blocks. Because the stackers can stack on both blockchains at the same time and get more money.

The problem was deliberately kept simple and explained, the following video goes into more detail about the “Nothing at Stake” problem:

Casper as a solution?
Ethereum tries to solve this problem with a system called Casper. Casper, Ethereum’s PoS system, is designed to punish those who generate a new blockchain.

Ethereum’s PoS system requires a certain amount of ether to validate transactions. If the Ethereum network now believes that a staker is lying or generating false data, part of the staker’s ether will be confiscated from the network. This creates an incentive to stay on the right blockchain.

Bitcoin Price Highlights
Bitcoin is located within a descending triangle on the daily chart
The price tests the support at $6,700 and is about to erupt

The Bitcoin price could not break the resistance at $7,800 and instead initiated an extreme downward movement, so the bottom level at $6,500 could be tested.
Bitcoin is testing the bottom of its bearish triangle on the daily chart and may see a breakout in the nearest future.

Technical Indicators Signals for the Bitcoin revolution

The 100 SMA is below the longer-term 200 SMA to signal that the path of the Bitcoin revolution leads to the downside. This suggests that selling pressure could be resumed. We have highlighted the resistance at $7,800 in recent chart analyses, which is extremely important for an upward move. Unfortunately, BTC was unable to breach the level and initiated a strong downward movement. We are finally approaching the bottom level of the highlighted range.

So far, the bottom at $6,500 an ounce has been confirmed three times and prevented further losses. It is important to observe the $6,500 level as a breach in the floor could lead to strong downward pressure. However, if the Bitcoin price bounces off this level, it could go back towards the $7,800 resistance in the near future.

Bitcoin Code Price Analysis

As you can see from the chart, the Bitcoin Code is moving in a descending triangle. The bottom at $6,500 could be reached and tested in the near future. The RSI is going down to signal that sellers have the upper hand. However, this oscillator is plunging into oversold territory to signal a slowdown in selling pressure.

The Stochastic is also moving south but has not yet reached oversold conditions, so further selling pressure may be possible. The main support level is at $6,500 an ounce, while resistance is at $7,800 an ounce.

For a good reason, TenX did not keep the token sale open, but limited it. The reason: If the sale had been open, there would have been a great danger that many investors would massively enter the sale phase. At the official stock market launch, there might have been too few investors willing to invest in TenX. As soon as TenX is traded on the Altcoin stock exchange, this could have resulted in a massive fall in prices. On this page we have compared some crypto exchanges for you. And also the amount of the investment was limited to a maximum of five million euros. The founders of TenX wanted to prevent the pay tokens from concentrating on a few large investors. Rather, they were interested in offering as many investors as possible the opportunity to get involved.

Backed by a Ethereum code

Originally, the trio from Austria and Thailand did not start under the name Ethereum code: As early as 2015 they had started their basic work under the name OnePay. Their idea at the time was to link a credit card with a Bitcoin Wallet, so that payments could be made anywhere. The founders took part in Fintech Singapore, a boot camp for startups. Just one year later, the makers had made it to the PayPal indicator in Singapore. Shanghai-based Fenbushi Capital, in which Ethereum founder Vitalik Buterin is a partner, had already invested one million US dollars in the young company in March 2017.

The four founders had also chosen the company’s headquarters in Shanghai carefully. Hosp says so at Trendingtopics:

“In Austria, people are struggling with whether credit cards can be accepted everywhere at all. We didn’t want to discuss whether this would make sense, we needed it as a prerequisite for our product.”

That’s why they didn’t want to implement the idea of TenX in Europe under any circumstances. One had concentrated simply and movingly on the asiatic area, because in Japan and Australia crypto currencies are very much more widespread than in Europe.

Thus the concept of a Bitcoin trader is to function

It is sufficient for the Bitcoin trader to enter his e-mail address and account number in order for the Smartphone Wallet to be tailored to him. Once this has been done, the user can fill his wallet with a digital currency. Because TenX uses the Bit-Go industry standard for data security, no unauthorized persons can access the private keys. Of course, the customer also needs a physical credit card. But he can order this very easily from the app.

As soon as the user has set up the wallet, he selects the desired crypto currency via the app and connects it to the card with a click. To ensure that TenX’s credit card is accepted in as many places as possible, the founders have entered into a partnership with MasterCard and Visa. Payments can then be processed in a matter of seconds via the COMIT network. A further advantage is that the digital currency is only converted into the respective national currency when paying. Until the credit card is used, the customer therefore has the option of selecting the currency that currently has the best exchange rate. He can therefore benefit from exchange rate fluctuations when paying with a card.

TenX credit card for digital currencies
bottom line
The TenX team has a real chance to get crypto currencies out of their current niche and make them suitable for everyday use. The big advantage of the idea behind TenX is that it combines the advantages of conventional currencies with those of digital currencies. In addition, there is an extremely positive start in the token sale phase, so that there is sufficient scope for development in the first few years. This is probably due not least to the fact that the four founders have thought through their concept extremely well down to the last detail. For example, the Austrian-Thai quartet has come up with a transparent fee structure from which users, the company and investors benefit. In this way, they do not – like many other providers from the world of digital currencies – rely exclusively on price increases. Rather, they create a real financial basis which, if the TenX card is sufficiently accepted, can guarantee solid growth for the company.

The only risk factor is the question of whether the card is accepted to a sufficient degree. TenX must not only reach those users who are fans of crypto currencies anyway. The big difficulty is likely to be to reach other consumers who have always paid with conventional currencies and credit cards. The Master or Visa holders

QUOINE was founded in 2014 by Mike Kayamori (CEO) and Mario Gomez Lozada (CTO). Kayamori was previously Senior Vice President at SoftBank Group and Chief Investment Officer of Gungho Asia. Lozada was the CTO of Merrill Lynch in Japan for 11 years, after which he became Information Manager at Credit Suisse Japan. The team also includes other specialists in the field of finance, often with a reference to Asia, as well as other software developers who take care of the technical side of token development. QUOINE is the first crypto currency company officially licensed by the Japanese Financial Services Agency. The developers already maintain the exchange platforms QUOINEX and QRYPTOS, which will be integrated into the network of the QASH token.

QASH Token advantages and disadvantages

Although the project took shape as early as 2014, further milestones still need to be taken on the way to the finished platform. For example, the developers still have to negotiate with the file-sharing services before the transactions can be processed via QUOINE. Will they even have an interest in it? The team is optimistic and emphasises that it is already connected to various online trading centres. The Korean swap meet Binance tries something similar by concentrating on small and rather unknown Altcoins. There is certainly no lack of competition. Gemini and Coinbase specialize in buying crypto currencies with Fiat money. Bancor’s blockchain can be used to freely convert ERC20 tokens (including the QASH crypto currency) and could become a serious threat.

A valid question is what incentive the developers want to provide to buy the QASH token. The crypto currency has only limited functions. On the page, developers describe how the crypto currency becomes the preferred coin for financial services, similar to Bitcoin. How they see it remains unclear. Later, the token is to become a general means of payment. There is no QASH Wallet of your own yet. Nevertheless, the share price has not developed badly so far. Probably you still have to give the development and the team some time. In any case, the idea has its advantages and the team is professional and already has a background in the area of trading with crypto currencies.

QASH Token Course with Bitcoin Code

The QASH crypto currency started with a value of 50 cents on the stock exchanges in late November 2017. At the end of the month, the Bitcoin Code price rose to over 1 euro per coin and then dropped to 50 cents in the first days of December. For a short time the value of the token reached 1 Euro in the middle of the month. The price remained at around 70 cents until the end of the year.

January 2018 was a particularly successful month for the crypto currency. For several days the price reached around 2 Euro per coin. At the end of the month the price fell again to 1 euro, in February even lower to below 1 euro.

With such a young crypto currency, it is difficult to make an accurate forecast. The token development has been running since 2014, but how the token will behave on the stock exchanges cannot be said yet. Before the platform is officially finished, the price will probably behave like most crypto currencies, lose value and gain value again.

Create QASH Wallet
There is no QASH Wallet of your own yet. Instead, you can use wallets that can hold ERC20 tokens. The MyEtherWallet is recommended in this respect. On the MyEtherWallet page, first enter a new password and then click on “Create New Wallet”. You get a keystore file and a private key, which you have to keep. You also get the address of the wallet. To unlock the MyEtherWallet you have to send a small amount of Ether to it.

Where can I buy the QASH Token?
There are a few exchanges where you can buy QASH tokens. The exchange against Bitcoin or Ethereum is possible on Huobi, Bitfinex, Qryptos or Gate. The purchase against Fiat currencies is possible on Quoine, Gate or Bitfinex.

Conclusion QASH Token
The idea of the QASH token definitely has something for itself and the team behind it is very confident. However, it will be a while before the full potential of QUOINE can be seen and at the same time you have to keep an eye on the competition. Other blockchain projects have also recognised the problem of lack of liquidity.

The QASH token is the crypto currency of the QUOINE LIQUID platform. With the development a global, decentralized platform is to be created, which is to solve the liquidity problems of the crypto currencies and simplify the purchase and exchange of coins.

The QASH crypto currency is an ERC20 token, i.e. it is based on the Ethereum blockchain. The primary function of the token is to serve as a means of payment within the platform for different services. In addition, holding tokens at the QASH Wallet should also be rewarded with discounts and give the opportunity to invest in initial coin offerings that take place on the QASH platform. According to the developers, the token has the potential to replace bitcoin as a means of payment.

The main goal

The main goal of the development on www.onlinebetrug/en is the QUOINE LIQUID platform. This platform wants to bring liquidity into the business of crypto currencies. Many traders face the problem that most crypto currencies are tradable on a small number of exchanges. If one wants to swap between the different coins, this project usually includes several accounts on different exchanges, several conversions to Bitcoin/Ether or the purchase by means of Fiat money. Or in short: It can be extremely cumbersome. In addition, there are several fees. The QUOINE LIQUID platform connects these file sharing services.

This is done, among other things, through the World Book. This collects all prices of the stock exchanges and presents them in a concise list. Thus the trader immediately sees the cheapest price of the desired crypto currency. At the same time, this system also gives unknown and small file sharing networks the chance to be discovered. The platform is to produce exchange pairs between two currencies with two “books”, the Internal Order Book and the External Aggregate Order Book, which could not otherwise exist, as the crypto currencies are spread over different exchange exchanges.

Usually one can only exchange an alternative coin for bitcoin or ether, but this should make it possible to create completely new exchange pairs. Several technologies make these transactions possible: Matching Engine is capable of processing several million transactions per second. The Cross Currency Conversion Engine automates the conversion of crypto currencies into each other and makes them possible. Finally, Smart Order Routing, which monitors and lists the file-sharing exchanges. Prime Brokerage is like the platform’s user interface. This gives you access to the file-sharing services as if you had an account there. This is the only way to make the exchange possible.

Blockchain App Store | Google Play and the Apple App Store are the most used mobile marketplaces in the world. This duopoly allows them to reduce the prices of all apps and in-app articles by 30%. Is that justified? Would a Blockchain App Store promote transparency?

Blockchain App Store and Market Transparency

In 2017, all App Stores recorded record sales and downloads. Downloads on both iOS and Android platforms increased year-on-year by 15 percent to nearly 50 billion worldwide. Total sales rose to 15 billion US dollars.

AppCoin wants to change this by using blockchain technology and changing the traditional app economy. The market and the battle for the best app on the App Store is now worth almost $77 billion and could even double by 2020.

What problems does a Blockchain App Store solve?

The App Stores are very inefficient due to many intermediaries between users and developers. These centralized platforms offer sales, investigation, and financial transactions, but have frustratingly opaque policies. The operators of the App Stores are also responsible for maintaining the apps and games in the store, but also enforce their own security measures and guarantee the integrity of every transaction made. Just like many other centralized systems, this model is flawed. Malware-infested downloads, inaccessible in-app purchases in low-end markets, data leaks and privacy concerns are some of the reasons why the user experience on mobile marketplaces is increasingly filled with risks and inconveniences.

In short, there are three important features of App Stores: advertising, in-app purchases and app approval/verification. Aptoide wants to move these three functions into the block chain and revolutionize the app industry with its App Store protocol AppCoins. AppCoins will act as a medium of exchange between end users and developers and improve user experience and market efficiency through unchanging smart contracts.

How are these problems solved?

To make advertising more transparent and affordable, AppCoins will eliminate all middlemen. A new user tracking method eliminates the need for CPI campaigns (cost per installation). They call it CPAt (Cost Per Attention). With this new model, a developer can directly reward a user. The user must spend at least two minutes in the app. The user receives AppCoins, which are stored in his wallets. The user can then use these appcoins for in-app purchases.

The blockchain will also help the AppCoins team reach the two billion smartphone users who do not have the necessary payment methods for in-app purchases. With their new model, users are rewarded (via CPAt campaign) with AppCoins, which they can spend in their favorite game.

Furthermore, the use of Blockchain App verifications by a developer reputation system makes them more universal and transparent. Your reputation is confirmed by means of a transaction in an auditable public register. A dispute resolution system is created so that the owners of AppCoins can create rankings for developers and the apps they publish.

The Team
The Aptoide Android App Store was already developed in 2009 as a flexible and open alternative to the Google Play Store. Today, it has over 200 million users worldwide who have downloaded more than four billion apps and games.

Conclusion to the Blockchain App Store
AppCoins is supported by Aptoide, one of the world’s most popular app stores. It is highly likely that by eliminating intermediaries, developers will be able to achieve higher returns on investment, increase the monetization potential of their product and communicate directly with their customers.
